There’s one thing Edward Luttwak wanted me to know, before he asked if I had a cell phone, and if so, could I turn it off and remove its battery, presumably if improbably so that he couldn’t be traced. We were sitting in his office library in his family’s sprawling Victorian home in suburban Chevy Chase, Md., full of books from floor to ceiling in Greek, Latin and from the modern era, volumes by Clausewitz, Walter Lacquer, Theodore Draper’s account of Iran Contra and thousands of others. These included a recent U.S. Military Balance survey, cataloguing the F-14s, F-7s, Phantoms and every other significant piece of military anti-air equipment estimated to be held by Iran — statistics that Luttwak looked up and ticked off during the course of our interview.
